Why Does the Inside of Car Windows Frost Over?

[DavidFitz]

Car windows frost over on the inside due to residual heat inside the vehicle after the occupants leave, which causes the temperature of the windows to be higher than the outside temperature, leading to condensation that freezes when it comes into contact with the cold. Methods to prevent the inside of the car windshield from frosting over include: 1. Parking the vehicle in a garage; 2. Covering the car with a car cover or using a large cloth to cover the windshield; 3. Spraying antifreeze on the windshield before parking. Methods to remove ice from the car windshield include: 1. Turning on the car's heater; 2. Using a hard plastic scraper to remove the ice; 3. Using a specialized de-icer; 4. Opening the car doors to ventilate after parking.
